Wearable Tools for Affective Remote Collaboration

Affective computing is the study and development of systems that can recognize human emotions and feelings. Emotions are always an interesting topic of research and these days researchers are trying to develop systems which can recognize, interpret and process emotions based on human physiological and neural changes for the development of well-being. As the market for wearable devices is expanding, it provides more opportunity of research in emotion sharing with remote person. This Master’s thesis investigates the possibility of using wearable devices for affective remote collaboration. Previous research about affective computing, affective communication and remote collaboration using wearable devices is reviewed before starting the design process. Three wearable devices were developed, evaluated and discussed, two for emotion sharing between remote people, and the third for preliminary research to explore if eye gaze information can increase co-presence in remote collaboration. Conclusions and Future work are discussed based on the results from the research evaluation

Gaze Awareness in Computer-Mediated Collaborative Physical Tasks

Human eyes play an important role in everyday social interactions. However, the cues provided by eye movements are often missing or difficult to interpret in computer-mediated remote collaboration. Motivated by the increasing availability of gaze-tracking devices in the consumer market and the growing need for improved remotecollaboration systems, this thesis evaluated the value of gaze awareness in a number of video-based remote-collaboration situations. This thesis comprises six publications which enhance our understanding of the everyday use of gaze-tracking technology and the value of shared gaze to remote collaborations in the physical world. The studies focused on a variety of collaborative scenarios involving different camera configurations (stationary, handheld, and head-mounted cameras), display setups (screen-based and projection displays), mobility requirements (stationary and mobile tasks), and task characteristics (pointing and procedural tasks). The aim was to understand the costs and benefits of shared gaze in video-based collaborative physical tasks. The findings suggest that gaze awareness is useful in remote collaboration for physical tasks. Shared gaze enables efficient communication of spatial information, helps viewers to predict task-relevant intentions, and enables improved situational awareness. However, different contextual factors can influence the utility of shared gaze. Shared gaze was more useful when the collaborative task involved communicating pointing information instead of procedural information, the collaborators were mutually aware of the shared gaze, and the quality of gaze-tracking was accurate enough to meet the task requirements. In addition, the results suggest that the collaborators’ roles can also affect the perceived utility of shared gaze. Methodologically, this thesis sets a precedent in shared gaze research by reporting the objective gaze data quality achieved in the studies and also provides tools for other researchers to objectively view gaze data quality in different research phases. The findings of this thesis can contribute towards designing future remote-collaboration systems; towards the vision of pervasive gaze-based interaction; and towards improved validity, repeatability, and comparability of research involving gaze trackers

Instructional Message Design: Theory, Research, and Practice (Volume 2)

Message design is all around us, from the presentations we see in meetings and classes, to the instructions that come with our latest tech gadgets, to multi-million-dollar training simulations. In short, instructional message design is the real-world application of instructional and learning theories to design the tools and technologies used to communicate and effectively convey information. This field of study pulls from many applied sciences including cognitive psychology, industrial design, graphic design, instructional design, information technology, and human performance technology to name just a few. In this book we visit several foundational theories that guide our research, look at different real-world applications, and begin to discuss directions for future best practice. For instance, cognitive load and multimedia learning theories provide best practice, virtual reality and simulations are only a few of the multitude of applications. Special needs learners and designing for online, e-learning, and web conferencing are only some of many applied areas where effective message design can improve outcomes. Studying effective instructional message design tools and techniques has and will continue to be a critical aspect of the overall instructional design process. Hopefully, this book will serve as an introduction to these topics and inspire your curiosity to explore further!https://digitalcommons.odu.edu/distancelearning_books/1003/thumbnail.jp

The Increasing Use of Portable Computing and Communication Devices and its Impact on the Health of EU Workers

[Excerpt] Portable computing and communication devices are widely used by workers from different occupations and their use is steadily increasing. The risks associated with working with portable devices and systems, for which at present no guidelines exist, differ considerably from those associated with working with visual display units at workstations. The latter are covered by the European VDU Directive and governed by a host of guidelines and recommendations within the EU Member States. In the light of the above, the study addresses the following issues: · To what extent are mobile communication devices used by the working population – how is such use growing in absolute terms and which types of workers are using them? · How is the technology behind these devices – hardware and telecommunications – developing, and how is the technology likely to evolve in the future? · Description of the possible hazards arising from the use of portable computing and communication devices and the risks to workers in terms of ill health and accidents. We also consider how the nature and extent of these risks will change in the future in the light of likely developments in technology and its use. · The implications of the use and development of mobile communication and computing devices for occupational health and safety management and for legislation and implementation in the context of European law concerning health and safety at work. · The scope is limited to work carried out in locations and environments that are impossible or difficult for the employer to control
